Biological function summary
The function of MAPK13 extends to its involvement in multiple cellular processes linked to stress responses. It forms part of a signaling complex that responds to extracellular stimuli. MAPK13 contributes to regulating inflammation by mediating the transcriptional activity of specific genes. Through phosphorylation it modifies other proteins and influences pathways that control cell growth and apoptosis. Cellular stress and environmental changes activate this kinase highlighting its role in helping cells adapt.
Pathways
MAPK13 integrates into the MAPK signaling pathway contributing to the transmission and amplification of signals related to cellular stress and inflammatory responses. It interacts with other proteins like MAPK14 (p38 alpha) within these pathways emphasizing its role in mediating cellular reactions to stress. The MAPK pathway influences the activity of transcription factors impacting gene expression and cellular outcomes. MAPK13 also plays a role in the p38 MAPK pathway emphasizing its connection within these essential signaling networks.

General info
Function
Serine/threonine kinase which acts as an essential component of the MAP kinase signal transduction pathway. MAPK13 is one of the four p38 MAPKs which play an important role in the cascades of cellular responses evoked by extracellular stimuli such as pro-inflammatory cytokines or physical stress leading to direct activation of transcription factors such as ELK1 and ATF2. Accordingly, p38 MAPKs phosphorylate a broad range of proteins and it has been estimated that they may have approximately 200 to 300 substrates each. MAPK13 is one of the less studied p38 MAPK isoforms. Some of the targets are downstream kinases such as MAPKAPK2, which are activated through phosphorylation and further phosphorylate additional targets. Plays a role in the regulation of protein translation by phosphorylating and inactivating EEF2K. Involved in cytoskeletal remodeling through phosphorylation of MAPT and STMN1. Mediates UV irradiation induced up-regulation of the gene expression of CXCL14. Plays an important role in the regulation of epidermal keratinocyte differentiation, apoptosis and skin tumor development. Phosphorylates the transcriptional activator MYB in response to stress which leads to rapid MYB degradation via a proteasome-dependent pathway. MAPK13 also phosphorylates and down-regulates PRKD1 during regulation of insulin secretion in pancreatic beta cells.
